IMPROVEMENT lN MACHINES FOR ETCHING GLASSWARE.

Specification forming part of Letters Patent N0. 219,813, datedSeptember 23, 1879 application filed July 29, 1879.

To all whom it may concern:

Be it known that I, JONATHAN HALEY, of Pittsburg, county of Allegheny,State of Pennsylvania, have invented certain new and useful Improvementsin Machines for Etching Glassware; and I hereby declare the followingtobe a full, clear, and exact description thereof, reference being had tothe accompanying dra wings, forming part of this specification, in whichFigure l is a side elevation of the machine. Fig. 2 is a longitudinalvertical section. Figs. 3 to 8 are details to be referred to.

This invention relates to certain new and useful improvements inmachines especially designed for etching glassware; and the inventionconsists in the general construction and combination of parts, as willbe hereinafter fully described and claimed.

To enable others skilled in the art to make and use my invention, I willproceed to describe the ex-act manner in which I have carried it out.

In the drawings, Arepresents a table, upon which the operating mechanismis mounted. 13 represents a circular plate, mounted on the upper end ofa vertical shaft, 1), passing down through the table A, and through across-plate, b, suspended by hangers a a from the under side of thetable A. 0 represents a forked standard secured upon the table A, andthrough which the shaft 1) passes, the circular plate resting on topofsaid standard. Upon the shaft 1), between the forks c c of said stand--ard, is mounted a gear-wheel, D, which meshes with a worm-gear on theshaft E, which is journaled in aprojecting plate, 0, of standard 0 andthe vertical standard a, said shaft being operated by a gear-wheel andcrank, a, mounted on one end thereof. The wheel 0 meshes with agear-wheel, 6 mounted on a stub-axle, d, secured to theslotted andadjustable bar d, journaled or pivoted to the upright standard 0. Thegear-wheel e meshes with a gear-wheel, f, mounted on one end of theshaft F, which is mounted in the extended-journal box g, secured on topof the standard 9, which is pivoted to the upright support Gr, securedon top of table A. Mounted upon the forward end of shaft F is a groovedblock, h, for the reception of the sliding chuck h, carrying the spindleh in which the etching-point h is mounted, and which passes through theslotted former g and extends over the circular plate 13, upon which theglassware to be etched is placed.

H H H are a series of interchangeable grooved dies or formers, securedupon the cross-plate b, below the table A, and over which passes thefriction-rollers i, journaled to a plate, I, mounted on the shaft b. Theobject of the interchangeable grooved dies or formers is to raise thecircular plate in its revolution, and thus produce different scallopsand other figures on the glassware. The sliding chuck h and the former gis for the purpose of giving different figures other than the commoncirculars, the slot through the former 9 being made of any desired shapeto suit figures required to be made on the glassware.

J represents a grooved former, which, when used, is mounted on thespindle h and former g is fastened on top of the journal-box g.

The shaft being then revolved, the grooved chuck coming in contact withthe circular plate B gives motion to the sliding chuck h and pointer7L3, thus forming almost any figure required on the glassware. When thegrooved former J is substituted for the slotted former, the slidingchuck h is provided with a pin, j,' which passes through a slot, 70, inthe grooved block h, a retracting-spring, l, returning the sliding chuckto its original position when raised by the revolving grooved chuck. Thesliding chuck can be provided with one or more points, as the figures tobe formed may require.

The object of the pivoted standard is to change the angle of the pointerto suit bevel of the article of glassware to be ornamented, the slottedarm 11 permitting of the intermediate gear-wheel, 0 being adjusted so asto keep the gear-wheels always in mesh, at whatever angle the pointermay be adjusted to. The pointer is always kept pressed against theglassware being ornamented by means of the spring m.

The operation of my improved machine is as follows The glass to beornamented is first covered with wax or other suitable substance, andthen placed on the revolving plate B, the hand crank-wheel is thenturned, which gives motion to shaft E, and also shaft F, revolving plateB and etching'pointer, which removes the wax or other substance in thepath of the pointer, thus producing the desired figures on theglassware, which are afterward cut in by acids, in the usual manner.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a machine for etching glassware, the combination, with therevolving plate B, of the shaft 1), provided with the plate I, havingfriction-rollers 1', and the interchangeable grooved dies or formers 11,substantially as and for the purpose shown and described.

2. In a machine for etching glassware, the combination, with therevolving shaft F, of the grooved block 11, mounted thereon, the slidingchuck h carrying the spindle h, in which the pointer h is secured, and astationary slotted or revolving grooved former, substantially as and forthe purpose shown and described.

3. In a machine for etching glassware, the combination, with therevolving plate B, of the shaft b, provided with the plate I, havingfriction-rollers i, interchangeable dies or formers H, shafts E F, andintermediate connecting mechanism, grooved block h, sliding chuck h,carrying the spindle ha, in which the pointer h is secured, and astationary revolving slotted or grooved former, substantially as and forthe purpose shown and described.
